Gas leakage automatic closed emergency safety cover structure

Abstract

The utility model discloses a gas leakage automatic closed type emergency safety cover structure, including the safety cover, the outside wall of safety cover is fixed with the fixed frame, the inside rotation of fixed frame is connected with the connecting plate, the bottom of connecting plate is fixed with the sealing plate, the bottom of fixed frame is fixed with the heat insulating plate, the right side of heat insulating plate is fixed with motor, the output shaft front end of motor is fixed with the rotation gear. This gas leakage automatic closed type emergency safety cover structure, if gas leaks, start motor, motor takes rotation gear and rotates, rotation gear takes transmission gear and rotates, transmission gear takes rotation lever and connecting plate and rotates, and the rotation of connecting plate takes sealing plate can cover the top of safety cover, and the output shaft of motor takes cam and rotates, and the extrusion of cam is relaxed to moving plate, and compression spring pushes sealing ring and rises, and sealing ring seals the outside of safety cover, so can prevent gas and leak.
